【摘要】 针对芯片只能在一定温度范围的环境下工作,超出一定的温度范围,芯片会失效等问题,提出了具有PID自整定温度控制功能的芯片加热器的研制.该加热器主要用于准确测试芯片在不同温度环境下的工作状态,有助于发现定位测试中遇到的误码、时序等问题.另外,该芯片加热器可以将失效的芯片加热至一定温度,使焊锡融化,拆卸下来,方便了仪器仪表的维护.更多还原

【Abstract】 In view of the problem that chips can work normally only within the fixed temperature scope and they can not work or are damaged outside the fixed temperature scope, a chip’s heater with PID self-adjustment temperature-control function is proposed in this paper.This heater is able to measure accurately a chip’s working state at various temperature and contribute to finding out wrong codes, time sequence,etc.during position measure.In addition,this heater can heat a bad chip in order to melt tin solder and remove this chip, which makes maintenance of an instrument more easy.更多还原
